Earth's crust components

Components of the planet we live on? What are the elements that make up the layer that appears to us in the preview?

The earth consists of 3 layers which are in order from outside to inside; The crust, the curtain, and the pulp, [1] and we can inspect it easily, and they are of two types

continental and oceanic

The continental crust consists of light-colored granite rocks, and the oceanic crust consists of darker basalt rocks, and the two types differ mainly in density, as the density of the oceanic crust is higher, so it is at a lower level compared to the continental crust. [1] In a study published in the journal Earth and Planetary Science Letters, Dr. Priyadarshi Chowdhury explained that the Earth's crust is still moving, but very slowly. [3] The earth's crust consists of various types of minerals and chemical elements, and the rocks on the earth's crust have several types: igneous, metamorphic and sedimentary, and here the chemical elements will be dealt with in detail, there are 12 different types of items with varying proportions, some of them are not common but they do exist

Among the elements contained in the earth’s crust, and then, scientists, leaders, flower, flower, flower, flower, proportion, flower, and 46.6% of the weight of the earth’s crust, and scientists for the first time in the earth. Watching included the burning of manganese oxide, and no one understood this gas exactly until the year 1775 when it was considered a chemical element, [6] and among the most prominent processes known, oxidation, oxidation; It is a reconstituted substance from the oxide of the substance, [7] and oxygen has many uses, the most important of which areIts use in making steel is used in making chemicals such as nitric acid and sodium peroxide. It is also used to make epoxythane, which is used to make polyester, and chloroethane, which is the raw material for PVC. Oxygen is used in a process known as oxygen welding. Silicon (Silicon) and its symbol (Si), the proportion of silicon in the earth's crust is 27.7% of the weight of the crust, which is the second highest percentage among its constituent elements,[9] as it is characterized by its strong interaction with halogens at high temperatures, forming halides, Silicon is used in several areas, most notably:

Brick and concrete in different types of brick and concrete in masonry. It is used in electronic devices as a semi-used material. It is used in solar energy. It is used in the formation of industrial organic silicon oxides in waterproofing and lubrication.

Aluminum Aluminum (in English: Aluminum) and its symbol (Al), the proportion of the element aluminum in the Earth's crust is 8.1% of the weight of the crust, which is the third highest percentage among its constituent elements,[9] and aluminum is commonly used in our daily lives due to its important properties that distinguish it, the most important of which is It does not rust, when aluminum is exposed to oxygen, a layer of aluminum oxide is formed on it that protects it from corrosion and rust. This process is called oxidation, and this is considered one of the most important positive properties of aluminum. It is widely used in kitchen utensils. It is used in food cans. It is used in buildings such as: windows

Iron (in English: iron) and its symbol (Fe), the proportion of the element iron in the earth’s crust is 5% of the weight of the crust, [] when iron is exposed to oxygen, it appears to oxidize, forming ferric oxide, which is a brittle brown substance, which is known as iron rust, and this is true practical Rust is worse than fresh water in it, and this characteristic in most matters that forces people to abandon it is an alternative, [13] and on this question from that iron in the fields more than 5000 years ago, and among its most prominent uses now: [13] It is used as a basic material in Building. It is an essential component of steel. It is used in the tobacco industry. It is used in the manufacture of auto parts. They appear in the production of parts of houses..
